8-channel Thermocouple Input Module

I-97018/S

8-channel Thermocouple Input Module

  Price:  $529.00  

Features

The I-97018 is an 8-channel universal Analog Input module with an RS-485 interface. Designed for thermocouple measurement and features automatic cold-junction compensation for each channel to ensure temperature output consistency and stable temperature output in the field. The innovative design of the enhanced model ensures that thermocouple measurement is more accurate than with the earlier design. Besides the thermocouple inputs, the I-97018 also supports voltage and current input. The voltage input range can be from +/-15 mV to +/-2.5 V. Up to 8 different types of Analog Input can be connected to a single module. Overvoltage protection of up to 240 Vrms is provided. The module also features per-channel open wire detection for the thermocouple and +4 ~ +20 mA input channels.
